How do you start an augur?

Excuse me, but could you clarify for me how one goes about starting an Augur? I'm relatively new to the world of cryptocurrency and decentralized finance, and I've heard that Augur is a popular platform for prediction markets. Could you provide me with a step-by-step guide or an overview of the process involved in setting up and using Augur? I'm particularly interested in understanding the technical requirements, any necessary software installations, and any potential barriers to entry that I should be aware of. Your insights would be greatly appreciated.
